HORSE HAY-RAKE SPECIFICATION forming part of Letters Patent No. 299,430,dated May 27, 1884.

' Application filed October 1-1, 1883. (No model.)

To all whom, it may concern:

Be it known that we, GEORGE H. SMITH and JOHN KIENARDT, citizens of theUnited States, residing at Dayton, in the county of Montgomery and Stateof Ohio, have invented a certain new and useful Improvement inHorse-Rakes; the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to which itapperreference being had to the accompanying drawings, and to theletters' of reference marked thereon, which form a part of thisspecification.

Our invention relates to improvements in the Hollingsworth horse-rake,or other forms using a rocking frame; and it consists in an automaticdumping device, the object being to dump the rake by asimple and cheapmechanism which consists of a curved bar provided-with segment-racks,and pivoted to the rear end of the rocker-arm, and supported in thefront by segment-gear attached to a rockTshaft extending partly acrossthe rake, and the device for engaging and detaching the lever thatoscillates the segmentgear for the purpose of throwing in and out ofgear the aforesaid rack-bar with the cogwheel attached to the hub'of thegroundwheel.

In the accompanying drawings, Figure l is a side elevation of ourimprovements as attached to a rake, and Fig. 2 is a plan View.

A is the wooden axle, and P the spindle which carries one of theground-wheels. To

the lower front edge of the axle A. is bolted The dotted line C, Fig. 1,

indicates the position of the ground-wheels.

' 'Io themetallic hub of one of the, groundwheels is attached thecog-wheel D, and a backing-ratchet may be interposed to release theground-wheel from the gear-wheel when a backward movement is given tosaid groundwheel, or, in case the device is applied to both wheels, topermit the rake to be operated while the machine is turning to the rightor left. i

I are the rocker-arms, which are pivoted on bearings over the center ofthe axle.

and we do hereby declare that the rocker-arm I. This rack-bar is curvedters Patent, is-

To the rod S, forming the the fastenings for the teet F.

To the rear end of the rocker-arms is attached the guide-bar G, to whichare attached staple-guides for the teeth, and to the forward end areattached guide-bars M and N, within which are supported guide-pins witheyes to receive the ends of the teeth, and around which, above the eyes,are spiral springs. The rear end of the rack-bar E is pivoted todownward and forward, passing-under the axle, and then upward to a pointnear the forward end of the rocker-arm. It is provided with asegment-rack adapted to engage the wheel D, and at its forward end-witha segment-rack engaging with a segment-gear, J, on a rock-shaftextending to near the center of the rake-head, where itis supported in abearing on the central rocker-arm. To this rock-shaft is attached thelever K at a point where it can be conveniently grasped by the hand ofthe operator,who occupies the seat indicated by dotted lines at L, Fig.2. When drawn backward, the pawl O engages a pin on the side of saidlever and holds the same in a fixed position, and in this position thelower segment-rack of the bar E engages the cog-wheel D of the hub,thereby causing the rake-teeth to be carried up until said pawl O isdisengaged by coming in contact with the cross-bar of the thills. Thecurved rack-bar then drops by gravity, thus throwing it out of gear withthe cog-wheel, and the teeth fall back to the ground to receive a newload. The faces of the lower or central center of their curve the pivotof the rocking frame, and the forward series the pivot of said rack-bar.

The detaching device may be varied; but

must be preserved.
